Annotations And Alerts

Annotations and alerts email

Thealertcondition annotation functionallows you to create custom alert conditions in Pine studies. One study may contain more than one alertcondition call.While the presence of alertcondition calls in a Pine strategy script will not cause a compilation error,alerts cannot be created from them.

Start being proactive with the new Data Driven Alerts capability from your iPhone app. Create your own personal data alerts in seconds and be notified when something interesting happens. Use annotation s to share crisp and clear insights with your team directly from your iPhone for immediate action anytime.

  1. Hello, I want to be able to create alerts with the use of SCOM and VCenter's PowerCLI. Has anyone been able to achieve this? Essentially I want to tie into VCenter's console, and grab the custom annotations define by the user, and feed the custom annotations back into the SCOM generated alert.
  2. The Apple Watch brings notifications to your wrist. Finally, you can get important notifications without looking at your phone—and you’ll get unimportant notifications, too. Here’s how to control your watch’s alerts.
  3. We are excited to announce that users are now able to see Annotation alerts in the Web Notifications Center. This enhancement centralizes Annotations notifications in a single place so that they can easily be referenced allowing users to Stay informed with one in-product destination for annotation alerts.

The alertcondition function has the following signature:

is a series of boolean (true or false) values used to trigger the alert.true means the alert condition is met and the alertshould trigger. false means the alert condition is not met and the alert should nottrigger. It is a required argument.
is an optional argument that sets the name of the alert condition as it will appear in TradingView’s Create Alert dialog box.
is an optional argument that specifies the text message to displaywhen the alert fires. The text will appear in the Message field of the Create Alert dialog box,and can then be modified before the alert is created.

Here is an example of code creating an alert condition:

The alertcondition function makes the alert available in the Create Alertdialog box. Please note that the alertconditiondoes NOT start alerts programmatically;it only gives you the opportunity to create an alert from itin the Create Alert dialog box. Alerts must always be created manually.An alert created from an alertcondition in the script’scode does not display anything on the chart, except the message when it triggers.

To create an alert based on an alertcondition, one should apply a Pine studycontaining at least one alertcondition call to the current chart, open the Create Alertdialog box, select the study as the main condition for the alert, and thenchoose one of the specific alert conditions defined in the study’s code.

When the alert fires, you will see the following message:

Modifying an alert¶

When an alert is created, TradingView saves the following information with thealert so that it can run independently in the cloud:

  • The study’s code
  • The study’s current Setting/Inputs (including modifications made by the user)
  • The chart’s main symbol and timeframe.

If you want any changes to this information tobe reflected in an existing alert’s behavior, you will need to either delete thealert and create a new one in the new context, or use the following steps to modify the alert.

If you have updated the study’s code or its Settings/Inputs, you may:

  • Click on the the alert’s line in the Manage Alerts list to bring up the chart and timeframe your alert is configured with.
  • Use the cog on the alert’s line in the Manage Alerts list to bring up the Edit Alert dialog box.
  • Select from the Condition dropdown menu the new version of the study you want to use. It will be the lowest instance of the study in the menu. Note that if you have changed the study’s Settings/Inputs, you will see those new values next to the study’s new version in the dropdown menu.
  • Click OK.

If you wish to change the symbol or the timeframe the alert is running on, you may:

  • Set your chart to the new symbol and/or timeframe you wish to apply to the alert.
  • Use the cog on the alert’s line in the Manage Alerts list to bring up the Edit Alert dialog box.
  • Select from the Condition dropdown menu the symbol and timeframe you wish the alert to be configured with, which should correspond to the chart you are currently on.
  • Make a new selection from the Condition dropdown menu, this time being the study containing the alertcondition you want the alert to run on.
  • Click OK.

Prometheus creates and sends alerts to the Alertmanager which then sends notifications out to different receivers based on their labels.A receiver can be one of many integrations including: Slack, PagerDuty, email, or a custom integration via the generic webhook interface.

The notifications sent to receivers are constructed via templates. The Alertmanager comes with default templates but they can also be customized.To avoid confusion it's important to note that the Alertmanager templates differ from templating in Prometheus, however Prometheus templating also includes the templating in alert rule labels/annotations.

The Alertmanager's notification templates are based on the Go templating system.Note that some fields are evaluated as text, and others as HTML which will affect escaping.


Data is the structure passed to notification templates and webhook pushes.

AnnotationsGrafana annotations and alertsAlerts
ReceiverstringDefines the receiver's name that the notification will be sent to (slack, email etc.).
StatusstringDefined as firing if at least one alert is firing, otherwise resolved.
AlertsAlertList of all alert objects in this group (see below).
GroupLabelsKVThe labels these alerts were grouped by.
CommonLabelsKVThe labels common to all of the alerts.
CommonAnnotationsKVSet of common annotations to all of the alerts. Used for longer additional strings of information about the alert.
ExternalURLstringBacklink to the Alertmanager that sent the notification.

The Alerts type exposes functions for filtering alerts: - Alerts.Firing returns a list of currently firing alert objects in this group - Alerts.Resolved returns a list of resolved alert objects in this group


Alert holds one alert for notification templates.

StatusstringDefines whether or not the alert is resolved or currently firing.
LabelsKVA set of labels to be attached to the alert.
AnnotationsKVA set of annotations for the alert.
StartsAttime.TimeThe time the alert started firing. If omitted, the current time is assigned by the Alertmanager.
EndsAttime.TimeOnly set if the end time of an alert is known. Otherwise set to a configurable timeout period from the time since the last alert was received.
GeneratorURLstringA backlink which identifies the causing entity of this alert.


KV is a set of key/value string pairs used to represent labels and annotations.

Annotation example containing two annotations:

In addition to direct access of data (labels and annotations) stored as KV, there are also methods for sorting, removing, and viewing the LabelSets:

KV methods

SortedPairs-Pairs (list of key/value string pairs.)Returns a sorted list of key/value pairs.
Remove[]stringKVReturns a copy of the key/value map without the given keys.
Names-[]stringReturns the names of the label names in the LabelSet.
Values-[]stringReturns a list of the values in the LabelSet.

Note the defaultfunctions also provided by Gotemplating.

titlestringstrings.Title, capitalises first character of each word.
toUpperstringstrings.ToUpper, converts all characters to upper case.
toLowerstringstrings.ToLower, converts all characters to lower case.
matchpattern, stringRegexp.MatchString. Match a string using Regexp.
reReplaceAllpattern, replacement, textRegexp.ReplaceAllString Regexp substitution, unanchored.
joinsep string, s []stringstrings.Join, concatenates the elements of s to create a single string. The separator string sep is placed between elements in the resulting string. (note: argument order inverted for easier pipelining in templates.)
safeHtmltext stringhtml/template.HTML, Marks string as HTML not requiring auto-escaping.
stringSlice...stringReturns the passed strings as a slice of strings.
